The orchestra and soloists of the Mariinsky theatre under the direction of distinguished conductor Valery Gergiev give a special concert at the London Coliseum to help raise funds for the people of Beslan and North Ossetia in light of the recent school tragedy. An all-Russian programme begins with music from Tchaikovsky's The Nutcracker and concludes with his Symphony No 6, Pathétique. Introduced by James Naughtie.
